Open source bug tracking system used by thousands of organizations worldwide for defect and issue management.

About Bugzilla

Bugzilla is a mature, web-based bug tracking system that has been powering software development teams since 1998. It helps teams log, track, and resolve defects through a workflow that supports assignments, status changes, dependencies, and comments. The system is built on a back end that uses MySQL, PostgreSQL, SQLite, or Oracle, and runs on Perl.

Key capabilities include a powerful search engine that lets you query by product, component, severity, priority, or custom fields. Bugzilla supports scheduled reports in chart and table form, email notifications, time tracking, and integration with version control systems like Git and Mercurial through commit hooks. It runs on Linux, Windows, and macOS, and can be extended with hooks or custom scripts.

Bugzilla is entirely open source under the Mozilla Public License, with no paid tiers or feature gates. It is best suited for development teams that want a self-hosted, no-nonsense bug tracker with a long track record of stability. Major adopters include the Mozilla Foundation, the Linux kernel team, and the Apache Software Foundation.
